“…Despite these challenges, more research is required to be conducted on this technology, as it holds promise for achieving near-zero CO 2 emissions in power generation and waste management. Certain technologies are being implemented to explore processes such as pyrolysis and thermal decomposition using devices such as a thermogravimetric analyzer, specially designed spectroscopy, etc., to analyze the processes' formation [84].…”

Carbon dioxide (CO2) emissions are a serious hazard to human life and the ecosystem. This is the reason that many measures have been put in place by the International Energy Agency (IEA) to reduce the anthropogenic-derived CO2 concentration in the atmosphere. Today, the potential of renewable energy sources has led to an increased interest in investment in carbon capture and storage technologies worldwide. The aim of this paper is to investigate state-of-the-art carbon capture and storage (CCS) technologies and their derivations for the identification of effective methods during the implementation of evidence-based energy policies. To this extent, this study reviews the current methods in three concepts: post-combustion; pre-combustion; and oxy-fuel combustion processes. The objective of this study is to explore the knowledge gap in recent carbon capture methods and provide a comparison between the most influential methods with high potential to aid in carbon capture. The study presents the importance of using all available technologies during the post-combustion process. To accomplish this, an ontological approach was adopted to analyze the feasibility of the CCS technologies available on the market. The study findings demonstrate that priority should be given to the applicability of certain methods for both industrial and domestic applications. On the contrary, the study also suggests that using the post-combustion method has the greatest potential, whereas other studies recommend the efficiency of the oxy-fuel process. Furthermore, the study findings also highlight the importance of using life cycle assessment (LCA) methods for the implementation of carbon capture technologies in buildings. This study contributes to the energy policy design related to carbon capture technologies in buildings.

“…Therefore, the dopant is crucial for the adsorption properties of the material. Studies have shown that doping S atoms can enhance the adsorption performance of materials mainly because the oxidized S functional groups generated in the carbon lattice can promote CO 2 adsorption through polar interactions. − The radius of the S atom is larger than that of the C atom, and thus, S doping introduces a large number of defects in the carbon skeleton, which result in the exposure of more N species . Currently, N/S-doped porous carbon materials are mainly prepared by mixing a precursor with N and S sources under the protection of an inert gas, followed by inducing activation, carbonization, and other processes.…”

In this study, we prepared N/S-codoped porous carbon materials via a one-step doping method using lignin as the carbon source, thiourea as the N and S source, and KOH as the activator. The synthesized material exhibited a rich N content and a certain S content. The important reason the CO 2 adsorption characteristic of the carbon materials were investigated by modulating the thiourea proportion and doping temperature.Results indicate that at a thiourea ratio of 1:4 and a doping temperature of 700 °C, the material exhibited an outstanding CO 2 adsorption capacity of 3.49 mmol/g. Various characterizations revealed that such a high adsorption capacity is attributed to the combination of a microporous structure and excellent surface chemical properties. The doping of S atoms resulted in the formation of effective active sites, increased the defect density of the material, and promoted the generation of N functional groups, thereby enhancing the efficiency of CO 2 adsorption. In addition, the material exhibits high CO 2 /N 2 selectivity and cycling stability. The overall results indicate that lignin-derived N/S-codoped porous carbon can serve as a potential adsorbent for CO 2 capture.

Coordination environment of metal atoms is core for designing high‐performance single‐atom catalysts (SACs), while metal‐support interaction also has an important effect on structure‐function relationship. Nevertheless, the interaction effect of metal‐support is mostly ignored. Through synergistic regulation of coordination environment and metal‐support interaction, Mn SAC with atom‐dispersed Mn–N2 sites on dopamine (DA) support is synthesized for sensitive and selective DA oxidation based on theoretical calculations and experimental explorations. MnN2 presents the more optimal catalytic site for DA oxidation than other coordination conditions, enhancing sensitivity including a wide range, a low limit of detection, and particularly a very low catalytic potential. The construction of Mn–N2 active sites on DA carbon promotes the coupling between Mn metal atoms and DA support, decreasing work function, facilitating electron exchange, shortening response time, and boosting selectivity. Both the catalytic mechanism of Mn SAC toward DA and the relation construction of catalyst's structure and catalytic function are established.
